CNC Router Noise - Page 2 - Vectric Forum
Apr 09, 2011· The Ridgid definitely helped reduce the router noise. That is the noise that the router motor itself generates. But the main reason I changed was because of the rpm/tone fluctuations that I was getting with the Porter cable. I believe, but I may be wrong, that the Ridgid has a feed back circuit that helps maintain rpm's under load.

Reducing noise from a grinder - Electrical Engineering ...
Aug 20, 2007· We are a plastic sheet extruder and we grind our scrap in a 40HP plastic grinder which grinds the sheets/thermoformed skeletons to small pieces. The grinder is old and generates a lot of noise. More than 110db while grinding. We did build a sound enclosure around it to reduce the noise but did not do much difference. We reduced around 10 -15 dB.
